Optical cable tractors are primarily classified based on their power sources and construction scenarios. In terms of power sources, there are diesel and gasoline-driven tractors, which adapt to different on-site power supply conditions. When classified by purpose and structure, there are mainly pipeline tractors for laying through pipes, overhead tractors for erecting high-altitude cables, and direct burial tractors specifically designed for ground or plow burial construction. These various models are designed to match different laying environments and ensure efficient and safe traction of optical cables.
